'30 it known that I, Enwoon B. Ame, a citizen of the United States, residing in -Philadelfhia, Pennsylvania, have invented. 5 certain improvements in Driers, of-which the following is a specification.

One object of my invention is to construct a drier for drying sheet material, such as near the sides as shown imFig. 3. pantasote, hav a coating on one face.

When material, such as antasote, is being construct the drier so thatxthe air in the compartment in which the material travels condenser. will be under pressure so that it-will be in As the material travels through the drier, econtact with the full width of the material. the air is circulated in the direction ofthe 15 In the accompanying drawings: arrow, Fig. 3, coming in contact with the Fig. 1 is adiagrammatic plan view. of my coated surface of the material, and, as the improved drying apparatus; I

At t e feed end of the drier is a series of steam pipes 13. These pipes are located. in

the compartment between the partition 2 an the rollers 11 for the material'a. The drier is divided by partitions'14 into four chambers, in the present instance, so that the-heat and moisture in the several .as it. passes steam pipes located between the partition and the supports for the material.
